Abstract

The single-cylinder foundation for offshore wind power has significant application potential in China’s wind power industry, particularly for deep-water regions, due to its ease of installation and excellent resistance to overturning. This paper investigates the response characteristics of the soil surrounding the barrel foundation subjected to combined wind and wave loading through numerical simulations. Results show that soil settlement gradually decreases with increasing horizontal distance from the foundation and also declines with increasing vertical depth, rapidly attenuating beyond a specific distance from the cylinder. The pore pressure distribution is positively correlated with the burial depth of the cylinder and increases significantly under cyclic loading. Horizontally, pore pressure decreases with increasing lateral distance from the cylinder, forming an elliptical high-pressure zone at the cylinder base, which reduces the shear strength of the surrounding soil. The soil around the suction cylinder foundation primarily undergoes asymmetric plastic deformation, leading to tilt-rotation shear damage, while the foundation itself remains undamaged.
